David Cameron is under pressure to reveal his links to 'Chinese interests' after it emerged that Beijing has welcomed his shock return to Cabinet.
The new Foreign Secretary's work for an investment fund 'engineered by the Chinese state' was raised by Sir Keir Starmer in the Commons while other MPs highlighted his controversial lobbying activities since leaving No10.
His foreign policy record also came under scrutiny during the first Prime Minister's Questions since the reshuffle, with his hosting of a G8 summit a decade ago called his biggest achievement by Rishi Sunak.
It came after Lord Cameron's 'unique understanding of China' was praised by a newspaper run by the Chinese Communist Party.

An article in Global Times described the 'golden era' of relations between the two countries during the Cameron premiership including the famous pint he enjoyed with president Xi Jinping in a pub near Chequers.
However, Lord Cameron's activities since quitting No10 the morning after the EU referendum were mocked by Labour leader Sir Keir at PMQs yesterday.
'A few months ago, the Intelligence and Security Committee said the now Foreign Secretary's role in a Chinese investment fund may have been – these are its words – 'engineered by the Chinese state'. When will he instruct the Foreign Secretary to give full public disclosure of his work for Chinese interests?'
Mr Sunak replied that he was 'delighted' at Lord Cameron's return, praised his 'unrivalled experience' and insisted he will 'go through the normal process with the independent adviser' on ministerial interests.
